  • Patent number: 7530986
    Abstract: A laminated ultrasonic waveguide and a method of fabrication thereof including stamping at least two pieces of sheet stock to form stamped parts of the laminated ultrasonic waveguide. The stamped parts are then laminated together to form a laminated ultrasonic waveguide for transferring ultrasonic acoustic energy along a longitudinal axis of the laminated ultrasonic waveguide. The laminated ultrasonic waveguide may be part of an ultrasonic surgical instrument having an active tip end-effector, which is placed in contact with tissue of a patient to couple ultrasonic energy transferred along the laminated ultrasonic waveguide to the tissue. The stamped pieces of sheet stock can also be stamped to form one or more channels extending along the length of the laminated ultrasonic waveguide. The laminated ultrasonic waveguide can also define a connector at a proximal end thereof to transfer ultrasonic energy into the laminated ultrasonic waveguide.

  • Patent number: 7341056
    Abstract: A portable oxygen supply unit for breathable air with an enhanced oxygen content has a tilt valve in a mounting cup on a pressurized container containing medical or aviators oxygen. A hollow housing is sealed to the mounting cup. The hollow housing is flowably connected to a mouthpiece and to an inlet for ambient air. A user can open the tilt valve with an actuator that is slidable in the hollow housing. When the valve is open, the pressurized oxygen flows into the hollow housing. As the user inhales through the mouthpiece the oxygen released from the container is diluted with ambient air drawn through the inlet for efficient use of the oxygen dispensed from the container.

  • Patent number: 7341058
    Abstract: An improved manifold assembly useful in patient ventilation/aspiration systems includes a stop cock valve with a hollow stem and a transverse port arranged to permit the stem to be rotated between open and closed positions. In both positions, a ventilating pathway is maintained through the stem between ventilator and patient connection ports of the manifold. In the open position the stem provides a travel pathway for a catheter between the patient connection port and an access port of the manifold. In the closed condition, the stem seals this travel pathway. The improvement provides an arrangement of structure operable to resist imparting shear damage to an inserted catheter, and to provide enhanced feedback to an attendant, as the stem is manually rotated into contact with the catheter.
